What is expiring and when
ISOVER has four product‑specific FDES/EPDs with March 2027 end dates. All sit in MasterFormat 07 21 16 Blanket Insulation and are published through INIES.
- Cladirol 35 Plus 112 mm, expiry 2027‑03‑30 (INIES)
- Cladirol 35 Plus 133 mm, expiry 2027‑03‑30 (INIES)
- Cladirol 35 Plus 154 mm, expiry 2027‑03‑30 (INIES)
- Comblissimo 375 mm, expiry 2027‑03‑14 (INIES)
ISOVER’s general EPD hub explains that product FDES are available on INIES and on the brand’s site, which is a good place to watch for refreshed files (ISOVER site, accessed 2026; Documentation index).
Are replacements already live
As of July 20, 2026, we do not see newer declarations covering these exact SKUs. Close cousins exist. For example, Comblissimo 465 mm carries a later validity into 2029, but it does not replace the 375 mm declaration. That nuance matters on jobs where thickness and declared unit need a one‑to‑one match.

What specifiers may choose instead
If these four lapse without renewals, expect teams to reach for blanket mineral wool with current EPDs in the same category.
- Johns Manville fiberglass batts have multiple UL‑verified EPDs current into 2027 across faced and unfaced lines.
- Owens Corning PINK Next Gen Fiberglas insulation holds an SCS‑verified EPD valid through August 2028.
- Knauf Insulation publishes several glass mineral wool EPDs with EPD International, including entries current to mid‑2029 in select markets.
These are not endorsements, just the practical shortlist specifiers recognize when an EPD checkbox must be satisfied.
Why timing matters here
In France, FDES on INIES are valid for five years. That is the standard window most program operators use for construction product EPDs, so renewals should be planned backward from the posted end date (INIES, 2026) (INIES, 2026). INIES also allows a managed postponement of takedown in limited cases when a verification contract and evidence are lodged at least three months before expiry, which can buy time if a verifier bottleneck hits (INIES, 2026) (INIES FAQ, 2026).
Commercial risk in plain view
When an EPD expires, teams do not just lose a marketing badge. They often lose access to the exact declared unit and scope needed for RE2020 models, LEED v5 submittals, or client carbon accounting. That forces substitution toward products with a current, third‑party verified file. In tight bids, that can swing a line item without even touching price. It’s annoying to discover after the fact because the sales pipeline rarely flags missing EPDs until the spec gets locked.
What to do this quarter
Map the four SKUs above against active opportunities where the 112 mm, 133 mm, 154 mm, or 375 mm thickness is baked into the design. If renewals are underway, set a clear go‑live date and communicate it to channel partners. If schedules slip, provide a pre‑approved alternate with an active declaration and equivalent assembly performance so estimators do not default to a competitor by habit.
Where to monitor for fresh files
Two places update first for ISOVER France products. The brand’s product pages and documentation center aggregate FDES downloads, while INIES remains the official register for FDES validity and versions (ISOVER site, accessed 2026; INIES resources). Keep both on your bookmarks bar, then check weekly as March approaches. Yes, that’s a little tedious, but it beats re‑working a spec at the eleventh hour.
The bigger lesson
EPDs are a sales enabler, not just compliance paperwork. Proactive renewal avoids last‑minute substitutions, keeps distributors confident, and preserves the brand’s position on public projects where the absence of a current file carries a carbon accounting penalty. Start renewal data collection early, verify the PCR path, and hold a clear handoff to the publishing operator. It’s boring project management that quietly protects revenue, which is kind of the point. Let’s not leave thier next win to chance.
